Supported machine learning providers

The Watson OpenScale service supports Watson Machine Learning as well as many third-party machine learning providers.

Use one of these supported machine learning providers to perform payload logging, feedback logging, and to measure performance accuracy, runtime bias detection, explainability, and auto-debias function as part of your model evaluation.

Watson Machine Learning
Azure ML Studio
Azure ML Service
AWS SageMaker
Custom (The custom machine learning framework must have equivalent functionality to Watson Machine Learning.)

Support for multiple machine learning engines

Watson OpenScale supports multiple machine learning engines within a single instance. You can provision them through the Watson OpenScale dashboard configuration or the Python SDK.

Adding providers using the Watson OpenScale dashboard

After you open Watson OpenScale, from the Configure tab, click Add machine learning provider.
Select the provider you want to add.
Enter the required information, such as credentials, and click Save.

Changing or updating details for machine learning providers

Click the tile menu the tile menu icon icon and then click View & edit details.

Adding machine learning providers by using the Python SDK

You can add more than one machine learning engine to Watson OpenScale by using the Python API wos_client.service_providers.add method.

IBM Watson Machine Learning

To add the IBM Watson Machine Learning machine learning engine, run the following command:

WML_CREDENTIALS = {
                   "url": "https://us-south.ml.cloud.ibm.com",
                   "apikey": IBM CLOUD_API_KEY
}
 
wos_client.service_providers.add(
        name=SERVICE_PROVIDER_NAME,
        description=SERVICE_PROVIDER_DESCRIPTION,
        service_type=ServiceTypes.WATSON_MACHINE_LEARNING,
        deployment_space_id = WML_SPACE_ID,
        operational_space_id = "production",
        credentials=WMLCredentialsCloud(
            apikey=CLOUD_API_KEY,      ## use `apikey=IAM_TOKEN` if using IAM_TOKEN to initiate client
            url=WML_CREDENTIALS["url"],
            instance_id=None
        ),
        background_mode=False
    ).result

Microsoft Azure ML Studio

To add the Azure ML Studio machine learning engine, run the following command:

AZURE_ENGINE_CREDENTIALS = {
    "client_id": "",
    "client_secret": "",
    "subscription_id": "",
    "tenant": ""
}
 
wos_client.service_providers.add(
        name=SERVICE_PROVIDER_NAME,
        description=SERVICE_PROVIDER_DESCRIPTION,
        service_type=ServiceTypes.AZURE_MACHINE_LEARNING,
        #deployment_space_id = WML_SPACE_ID,
        #operational_space_id = "production",
        credentials=AzureCredentials(
            subscription_id= AZURE_ENGINE_CREDENTIALS['subscription_id'],
            client_id = AZURE_ENGINE_CREDENTIALS['client_id'],
            client_secret= AZURE_ENGINE_CREDENTIALS['client_secret'],
            tenant = AZURE_ENGINE_CREDENTIALS['tenant']
        ),
        background_mode=False
    ).result

Amazon Sagemaker

To add the AWS Sagemaker machine learning engine, run the following command:

SAGEMAKER_ENGINE_CREDENTIALS = {
                   'access_key_id':””,
                   'secret_access_key':””,
                   'region': '}
 
wos_client.service_providers.add(
        name="AWS",
        description="AWS Service Provider",
        service_type=ServiceTypes.AMAZON_SAGEMAKER,
        credentials=SageMakerCredentials(
            access_key_id=SAGEMAKER_ENGINE_CREDENTIALS['access_key_id'],
            secret_access_key=SAGEMAKER_ENGINE_CREDENTIALS['secret_access_key'],
            region=SAGEMAKER_ENGINE_CREDENTIALS['region']
        ),
        background_mode=False
    ).result

Microsoft Azure ML Service

To add the Azure ML Service machine learning engine, run the following command:

service_type = "azure_machine_learning_service"
added_service_provider_result = wos_client.service_providers.add(
        name=SERVICE_PROVIDER_NAME,
        description=SERVICE_PROVIDER_DESCRIPTION,
        service_type = service_type,
        credentials=AzureCredentials(
            subscription_id= AZURE_ENGINE_CREDENTIALS['subscription_id'],
            client_id = AZURE_ENGINE_CREDENTIALS['client_id'],
            client_secret= AZURE_ENGINE_CREDENTIALS['client_secret'],
            tenant = AZURE_ENGINE_CREDENTIALS['tenant']
        ),
        background_mode=False
    ).result

Producing a list of machine learning providers

To view a list of all the bindings, run the list method:

client.service_providers.list()
